NCD Calculation

NCD (Net Coding Data) is the coding-data map ISTA uses for each ECU in the vehicle. Upload the FA and SVT XML files exported from E-Sys or ISTA and we return the calculated NCD for that vehicle.

HOW IT WORKS

  1. 01
    Export both files

    Save the FA and SVT reads as XML from your diagnostic tool.

  2. 02
    Upload them together

    Both files are parsed on our side; the VIN is read from the FA.

  3. 03
    Download the NCD

    Import the result into your coding workflow.

FAQ

What if the files do not match?

Processing stops with an error, because the FA and SVT must describe the same vehicle. Re-export both from the same session and try again.

Can I use files from another car?

No. The VIN inside the FA identifies the vehicle; mismatched files produce invalid coding data.

Which tool versions are supported?

Standard FA and SVT XML exports from E-Sys and ISTA. If your tool writes a different format, send us a sample on WhatsApp first.
